CLOGKWORKS.

To all whom it may concern.

Be it known that ll/IARSHALL' Q. Rose, a citizen of the United States, residing at Oregon City, in the county of Clackamas and State of Oregon, has invented certain new and useful Improvements in Clockworks, of which the following is a specification.

My invention relates to improvements in clock-works and has particular reference to an adjustable stop or banking device for the verge, and also to improvements in the vergewire.

An important object of the invention is to provide a bank or stop for the verge, which will maintain the verge in mesh with the escape wheel, at the proper depth.

A further object of the invention is to pr0- vide a verge stop or bank which is bodily adjustable, and also having means whereby one arm of the verge is adjustable with relation to the other arm, whereby the device may be used in connection with verges of different sizes.

A further object of the invention is to provide a verge-wire having a peculiar friction joint, whereby when the pendulum is given a fair swing, such joint will hinge and the pendulum will quiet down to its proper plumb and therefore the clock will be in beat.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of devices embodying my invention,

Figure 2 is a perspective view of the vergewire and associated elements, parts separated, and

Figure 3 is a similar view of the verge stop or bank, parts being separated.

In the drawings, whereby for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the frame plate of a clock-works. Rotatably mounted upon this frame plate is an escape-wheel, of any well known or preferred type, which is driven by the usual train of gears, not shown. Pivoted upon a shaft 7, beneath the escape-wheel, is a verge 8, which may be of any well known or preferred type.

My invention resides partly in the provision of a verge stop or bank, including an Specification of Letters Patent. Patented J ne 20, 1922 Application filed August 122, 1921. Serial No. 491,668.

The numeral 14 designates a co- These openings are screw'-threaded for receiving a screw 18, which adjustably clamps them together. It is thus seen that the entire stop or bank may be adjusted upon the screw 11, and the arm 14 may be adjusted toward or away from the arm 12.

The numeral 20 designates a pendulum, carried by a rod 21 secured to a supporting spring 22.

My invention also resides in a verge-wire 23 embodying an upper section 24 rigidly secured to the verge 8, upon one side of its pivot. The section 24 is provided at its lower end with a transverse cylindrical head 25, rigidly secured thereto. This head is inserted within a cylindrical socket or sleeve 26, rigidly secured to the lower section 27 and has frictional engagement therewith. The socket 26 is longitudinally split at its top and is provided at its edges with notches 28, adapted to receive the upper section when the head 25 is turned therein. At its lower end, section 27 has a loop 29 receiving the pendulum rod 21. In operation, the extensions 13 and 15 restrict the swinging movements of the verge 8, maintaining the same in mesh with the escape-wheel at the proper depth. The sections 2a and 27 are rigid, and the friction joint embodying the head 25 and the socket 26 is normally sufficiently strong to afford a stiff joint between these parts. However, in starting the clock the pendulum is given a fair swing, and the friction joint will bend or hinge, whereby the verge-wire will acquire the proper length. The pendulum-will now quiet down to its proper plumb and the clock will be in beat.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred embodiment of my invention, and that the various changes in the shape, size and arrangement of parts, may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. The combination with the escape-wheel of a clock-Works, of a verge pivoted to engage the teeth of the escape-wheel, an arm having a finger provided with a laterally extending stop element arranged upon one side of the verge, a second finger carried by the arm and having a laterally extending stop element arranged upon the opposite side of the verge, and adjustable means for supporting said arm whereby the arm may be angularly adjusted.

2. The combination with the escape-wheel of a clock-Works, of a verge, pivoted to engage the teeth of the escape-wheel, an arm having a finger provided with a laterally extending stop element arranged upon one side of the verge, a second finger carried by the arm and having a laterally extending stop element arranged upon the opposite side of the verge, means whereby the second finger may be moved toward and away from the first named finger, and means to support said arm.

3. The combination with the escape-wheel of a clock-Works, of a verge, pivoted to en gage the teeth of the escape-wheel, an arm provided at one end with a longitudinal slot and having a finger at the opposite end carrying a lateral extension arranged upon one side of the verge, a second finger having a lateral extension arranged upon the opposite side of the Verge, a pivot element connecting the first and second fingers and adapted to clamp the same together, and a clamping element extending within said slot of the arm.

In testimony whereof I aflix my signature.

MARSHALL O. ROSE.
